APPARATUS FOR APPLYING NONSLIPPING MATERIAL T0 FLOOR COVERINGS.

Application led March 23. 1925. Serial No. 17,627.

The present invention relates to an apparatus for applying anon-slipping material to ioor coverings. An object of the 1nvention isto make it possible to applya non-slipping element to a Hoor covering 1nsuch a manner that the nonslipping element is edectively attached to thecovering without the use of a large amount of volatile solvent. Afurther object of the invention is to provide an apparatus which willutilize a non-slipping element in a viscous rather than in a, freelyiowing liquid condition. A still further object of the invention is toprovide an apparatus which will lay a viscous non-slipping element instrips upon the back of the floor covering with a pressure that willcause the viscous material to penetrate the oor covering.

To these and other ends, the invention consists of certain arts andcombinations of parts, all of Whic will be hereinafter decribed: thenovel features being pointed out in the appended claims.

In the drawings:

Fig. l is a perspective view of the apparatus for applying thenon-slipping element;

Fig. 2 is a perspective view showing the apparatus in one position as itis eing moved over the rear face of a floor covering to apply thenon-slipping element thereto in strips; and

Fig.. 3 is a transverse section throughthe apparatus and floor covering.v

rior to this invention, it has been suggested to apply rubber in aliquid state to the rear face of a oor covering to prevent the slippingof the covering on ioors. This rubber has been applied in a freelyflowing condition, necessitating the use of a large amount of solvent,and at the same time reventing the formation of definitely de ed areasof the non-slip ing element on the iioor covering. Accor ing to thisinvention,-

the non-slipping element, rubber composition ,or other material, isapplied to the oor covering in a viscous condition under pressure and indefined areas.

, An apparatus for'carryin out this inven- -tion may consist of adistributing member in the form of a box or receptacle 1 with a cover ortop 2, having a slip-fit connection,

in this instance, with the body. This cover acts as a distributing headand is provided with a plurality of elongated slots or openings 3,arranged in parallel relation and having one end 31 of each slot inspaced relation to the adjacent corner of the hanged cover, While theother end 3b extends'throughout the top surface and onto the flange `ofthe cover, this flange serving as a vertical`wal1 for the distributinghead. The non-slipping element 4 in viscous form is arranged in thereceptacle or container 1 andthe latter may have in its bottom Wall avent or opening 5 through which air at atmospheric pressure or underpressure above that of the atmosphere may enter the distributing memberwhen. the latteris inverted on the floor covering.

In the use of the invention, the carpet or floor covering is turned uside down on a suitable support and the stantially filled, is invertedso as to resent `the discharge openings 3* in strips 7, as

shown in Fig. 2, the openings 3b defining the cross sections of thestrip. Owing to stributor, subthe discharge openings 3b formed in t ewall i The distributor is then i the fact that a body of viscousmaterial is in the distributing head it exerts its pressure` on thematerial passing through the slots 3, and the viscous material is forcedinto the interstices of the floor covering under pressure. As the headmoves the material issues from the discharge orifices 3" in stri s whichtake a cross sectional form of the discharge orifices. Owing to the factthat the material is in a viscous condition it quickly dries.Furthermore, it does not require much solvent and it is possible to molda strip in a defined yarea on the iioor covering. As it is placed on thecovering under pressure, the` material firmly unites with the thatpeeling oft' is eliminated.

coveringlso Applicant has provided a receptacle, the

general natureof which is closed except for the provision of the dischare openings in the bottom and side Wall. T is ermits the receptacle to bemoved over the ing and When the end of the Hoor covering is reached tobe inverted so as to maintainv the contents in the receptacle. Whenoperating the receptacle is vented so that the pressure of theatmosphere is admitted to the upper surface of thermateriallin orderthat suf icient pressure for discharging the material may be obtained. fu
